High-resolution through-wall ghost imaging algorithm using chaotic modulated signal

Abstract

In this paper, a novel high-resolution through-wall ghost imaging (TWGI) algorithm is proposed for detecting targets hidden behind walls. By using chaotic modulated signals, ghost imaging (GI) derived from optical image reconstruction applications is introduced and applied in through-wall imaging (TWI) scenarios to achieve high-resolution imaging capability. The scattering coefficients of the target imaging plane are treated as levels of brightness in the proposed algorithm, whose spatial distribution can be retrieved by processing the estimated electromagnetic (EM) field at the target imaging plane with the reflected signal captured by a single receiving antenna. Simulation results are presented to show the effectiveness and high quality of reconstruction results by using the proposed TWGI algorithm.
